AB  - This study surveys the literature in the field of intersystem handover algorithms as applied in
Heterogeneous Wireless Networks (HWNs) over the previous years. Intersystem handover algorithms have
been comprehensively studied and applied in HWNs, however, this is the first attempt to put in viewpoint the
numerous efforts in form of a survey. In order to provide an inclusive survey of the existing literature. We
examine current state of the art intersystem handover algorithms according to their common methodology
applied in order to reduce intersystem handover delay while reducing packet loss during the handover process
between RATs in HWNs. Additionally, we present a clear understanding of this active research area, by
identifying a clear classification and guidelines used when intersystem handover algorithms are designed.
Furthermore, we outline strength and weakness of existing solutions and highlight the key open research areas
for further development. This comprehensive survey act as a basis starting point and a guide for everyone
enthusiastic to explore into research on intersystem handover algorithms in HWNs. Finally, the study presents
the conclusion.
